2.5-Inch Cat-Back Exhaust System

The ARK Performance downpipe is engineered to maximize power from your 3.3T engine. Constructed from 2.5-inch SUS304 stainless steel piping with a fully polished finish and CNC machined flanges, this component is designed for a direct bolt-on installation, integrating seamlessly with the OEM stock factory exhaust or any aftermarket cat-back exhaust with OEM fitment. This downpipe system replaces the stock catalytic converter(s) and is intended for off-road and racing use only. It is not legal for highway use on pollution-controlled motor vehicles and is restricted for purchase in California. Use is limited to sanctioned racing events. A signed waiver form is required for purchase, attesting to its intended use for racing and off-road applications. The kit includes necessary hardware for installation, such as gaskets, bolts, and nuts. While designed as a bolt-on, it replaces restrictive factory downpipes to improve exhaust flow and performance. Users have reported that the installation process can take approximately 1-2 hours.
